Problems solved by technology

[0005] In the food chain cultivation method of pond cultured fish, forage is used as the biological link base of the food chain, and the forage raw material is easy to obtain, especially in rural areas, and these forage can also be fresh Straw forage, which also solves the problem of straw disposal, and can obtain sufficient forage sources

Embodiment Construction

[0008] The cultivating method of pond culture fish food chain is carried out according to the following steps.

[0009] First, collect a large amount of fresh forage, which can also be fresh withered forage and straw, such as freshly harvested straw and wheat straw;

[0010] two, Bundle the fodder into 30 kg bundles and wrap them with plastic nets so that they cannot be loosened. Forage that is too dry should be sandwiched with some cow dung to make it easier to ferment;

[0011] three, Float the bundled forage evenly on the water surface of the pond and connect each other with a rope net to fix the position;

[0012] Four, The forage begins to be decomposed, fermented and rotted by microorganisms after being exposed to sufficient water and air on the surface of the pond for a week;

[0013] Fives, Put a small amount of semi-dried cow dung on the top surface of each bundle to inoculate with maggots and parasites. The growing maggots and parasites feed on the fe...

Abstract

The invention discloses a method for cultivating food chains for cultured fish in ponds. The method includes that a large quantity of forage is separately bound to obtain bales with the weights of 30 kilograms, the forage bales float on water surfaces of the ponds, are in sufficient contact with water and the air and accordingly are easy to ferment and rot, fly maggots and parasites are inoculated on fermented and rotten substances and eat the fermented and rotten substances, the quantities of the fly maggots and the parasites are continuously increased, the fish in the ponds floats to the water surfaces to compete for the fly maggots and the parasites and eats the fly maggots and the parasites, and the biologic food chains in the ponds can be formed.

Description

technical field [0001] The invention relates to a method for cultivating a fish feed biological food chain on the surface of a pond, and belongs to the technical field of aquaculture. Background technique [0002] my country is a big country in aquatic production, and aquatic production includes aquaculture, aquatic fishing, etc. Aquaculture is also an important part of my country's agricultural production. Fish farming in ponds is an important part of aquaculture in my country. Fish in ponds are raised on feed. Generally, fish feed contains less protein and more starch or other energy, which makes the fish grow slowly and the meat quality of the fish cannot be improved. The cost of feed investment in pond culture is also high, and the economic benefits obtained by farmers are not obvious. In fact, in pond culture, the surface of the pond has a wide space for comprehensive utilization. For example, many farmers raise ducks in the pond, and some fish like to eat duck dropp...
